Only one man can claim to have been hands on with Miranda Kerr, Irina Shayk, Scarlett Johansson and most of the Victoria's Secret models' bodies. No, sit down Adam Levine, we're taking about personal trainer Justin Gelband.

Don't do workouts like a man

"When I moved to LA, I was watching all of these men training women like men, and it was driving me crazy because women's bodies are 100 percent different than men's, period," he told Fashionista.

"Your structure is different. Your physicality is different. Your minds are different. Your goals and objectives are different, so how are you going to be the best that you can with your own body if a man is training you just like he would a man?"

Pay attention to your workout form

"No one is perfect, but to do something totally wrong that's going to hurt you, it just doesn't make any sense...People don't care about how to form or how the exercise is performed, and to me that's more important than anything else."

Getting the body of your dreams takes time

"Irina, Candice, Erin, Miranda, Behati and Lily - all the girls that I have been working with over time to build my career - it took us three months to build their foundations and another three to six months to really get them on to be where they're at," Gelband explains.
